To all whom# may concern: Y

Be it known that I, J oHANN HEINRICH LANDGREBE, of Cassel, in the GermanEmpire, have invented a new and useful Improved Tap for Water or other Liquids, (for which I have obtained Letters Patent in Great Britain No. 13,034, dated July 4, 1893,) of which the following is a specification, referencebeing had therein to the accompanyingv drawings. This invention relates to an improved tap for water and other liquids that will close automatically to stop the supply of liquid.

Figure 1 shows a front elevation of the tap,

' while Fig. 2 is a longitudinal section.

In carrying out my invention I- provide a tap-body of the ordinary kind with an inlet h and outlet/i for the liquid at each end. I pro- Vide thetap with screw-threads or like devices by means of which the tap can be attached to a service-main and distributingpipe respectively. Near the middle of the tap is a seating a and a seating w, the former constituting the valve-seat proper, while the latter serves as a means for supporting aiiexible valve e and a bell-shaped cover b, which .is attached to the seat by screws s. Situated in the interior'of the casing b is a plunger d, which is free to rise and fall, as will be presen'tly described. Attached tothe casing b by screws n and clamps mis a bracket c, carrying a spindleA lc, on which is pivoted a le-- verf. At one end the lever is provided with a weighted handle g, while at the other is formed a cam-surface o.

l k brings a portion of the cam-surface o which In operation the lever f, with its weighted handle g, is lifted, and, turning round, the pin is nearer to the latter, opposite to the plunger i CZ. The plunger, owing to the pressure of the 40p water on the under side of the flexible disk e, is forced upward, so that a passage is left for the water. A set-screw n is-used to regulate the height to which the lever f can be lifted. In closing the tap it is only necessary to tilt the lever f or let go of the handle, when theV weight gwill descend and.- cause the camsurface o to press on theV plunger d, and so force the flexiblewasher e to its seat.

It will be understood that thedetails of the tap may be varied without departing from the essential features-of my invention. For inv stance, the bracket c may be joined in one piece with the bell-shaped cover b, while the lever f maybe arranged in different positions, as found most convenient.

- What I claim,and desire to secure by Letters Patent of the United States, is

` A tap for water or other liquids comprising in its construction an inlet and outlet port' bracket and provided at its pivoted end with a cam face adapted to act upon the plunger, a weighted handle mounted upon the opposite end of said lever, and an adjustable 'set screw n tapped in the'upper portion of said bracket and operating to limit the Vertical movement of said leverand plunger, substantially as described.

' In witness whereof I have hereunto set my hand `in presence of two witnssees.

JOHANN HEINRICH LANDGREBE.
